Has anyone ever seen this before?

I have to admit, when I saw this at the hospital, I had to stop and see what it was.  It is a sign... by a door... which lets you know that this is a staircase.  I had never seen that before and wanted to share it.  It may not be new to you, but I have never seen it before.

It just goes to show, you can learn something new everyday.  Or... don't say it... but you can teach an old dog new tricks.  Yeah, don't go there.
